This has got to be one of the worst reviews I have ever read on the E Zone. It seems to have been hastily thrown together with little to no review. It misuses terminology, is confusing, and at times is incorrect. If you are new to LiPo battery charging please get your information elsewhere.
I'll probably get a lot of grief for saying the above, so I will present several examples.
- Nowhere is the supported LiXX cell count given, I had to count the pins on the balance connector to discover this basic feature information.
- Incorrect terminology and/or lack of understanding, balancing is done based on cell voltage and not charge. "As soon as the balancing lead is attached, the charger will begin trying to balance the battery by very slightly discharging cells with higher charges."
- Some pictures in the "Data Views" section appear to be duplicates and do not match the captions
- Incorrect use of units and misinformation, volts are not equal to amps and termination current is C/10.
"When the Triton 2 EQ charges using the CC/CV method it reduces the voltage to about 0.1 amps near the end of the charge."
- Instructions that contradict the charger's manual and if followed will lead to reduced battery life. Note that this charger does not appear to have a storage mode and will discharge a LiPo to 3 volts per cell. "It is recommended that when your Li batteries are going to be stored that rather than charge them for storage, you should safely discharge them and then store." The manual states "LiPo/Ion batteries should be stored with about 30%-50% of capacity."
- Misinformation, new LiPo packs should be charged before first use. "You may or may not discharge your Li batteries. It is recommended for storage, but the ability to discharge the Li prior to the first use is a good idea."
- Confusing information that seems out of place and not relevant. I'd especially like to know what "This draw down is also called internal resistance." means.
"For the FlightPower EONLITE I have a 2100 mAh 3S 11.1V pack capable of 42.0 amps @ 20C continuous and 84.0 amps at 40C as a maximum burst. The formula of 2100 mAh = 2.1 amp hr x 20C = 42 amps the battery is capable of producing. At 40C I have 2100 = 2.1 amp hr x 40C = 84 maximum burst amps. This draw down is also called internal resistance."
- Confusion that contradicts the manual, discharge rate is limited to 20 Watts and 3 Amps. The C/5 discharge rate is suggestion for accurate measuring of capacity, it is not a limit. "The usage draw differs significantly from the balancing draw down. You can increase the amperage draw much higher than 0.5 amps to a 3.0 amp discharge but this is a balancing discharge and that is why we do not have available higher amperage draw numbers."
- The quote in #8 is contradicted and rendered confusing by this statement made just prior to it. There even appears to be a self-contradiction in the following quote, can I use 1 Amp or not and what about 3 Amps? "A word on the discharge formula: one method provided is C/5/1000 to obtain a mA value. I found this way too slow and pushed it to 1 amp. Even at this the discharge, it was very slow. But this is not a full power discharge and rather a balancing discharge across all the cells. Don't be too quick to increase the amps."
- No mention in the body of the review that the output power when using the DC input is 120 Watts, only the output power when using the AC input was cited.
- No mention of the quality of the manual.
- The "Keeping my hat on:" section does not include significant negatives such as no storage mode, a DC power cord that cannot be unplugged and no PC interface for recording data and performing firmware updates.
- Lacked depth in that a multi-chemistry charger was only tested with LiPo and NiMH packs.
- Miscellaneous typos (eg. using the term "cell" instead of "pack") and tables with no context or explanation provided.
- Awkward sentence structure and grammar that made the review a challenge to read and difficult to understand.
Overall I am disappointed by the quality of this review, that it was submitted for publishing, and that it was approved for publishing on the E Zone. I have even read other reviews by this same author that were better than this one. If you are not qualified or lack the time to do a proper review then perhaps the charger should returned to Great Planes.
